Standard Edge Switches
Standard Edge Switches
• For use in clean, temperature-controlled environments
such as offices and wiring closets.
• Feature the same heavyweight metal case as our more robust
models.
Hardened Edge Switches
• For use in dusty or dirty environments—ideal for demanding
industrial applications.
OVERVIEW
• Rated for a temperature range between -13 and +140°F
(-25 and +60°C).
• The metal case acts as a heat sink so no internal airflow
is needed for cooling.
• Sealed case resists contaminants such as dust, dirt, moisture,
smoke, and insects.
Extreme Edge Switches
• Robust units for outdoor use require protection only from direct
rainfall or standing water.
• Ideal for applications such as traffic-signal control, or for sensors
or surveillance cameras in outdoor plants.
• Rated for above-the-ceiling plenum installation.
• Rated for extreme temperature ranges of -40 to +167°F
• Rated for extreme temperature ranges of -40 to +167°F
(-40 to +75°C).
• Features a sealed case, which uses its own metal shell
as a heat sink.
Multiple power options
• Standard models come with AC power adapters only,
in a choice of 115 or 240 VAC.
• AC-powered Hardened and Extreme Switches feature robust
100- to 240-VAC power supplies.
• DC-powered Hardened and Extreme units have internal screw
terminals for connec ting DC power in addition to an AC power
jack. Because these models have dual power connections, you
can use them simultaneously with both your DC power supply
and an AC power adapter (sold separately) to provide redundant
power input.
